Abstract

The invention relates to a lock, which is characterized in that a lock-core shell is arranged in an action through hole of a door-handle cover of the lock; the other end of the lock-core shell is sleeved with a lock-core rotating shaft; a screwing component combines the lock-core rotating shaft with a lock core at a corresponding end together; the other end of the lock-core rotating shaft is matched with a push-contact end and is encased in a jacking block provided with an oblique edge; an elastic component is encased in a hole of the end provided with the oblique edge of the jacking block; the elastic component can hold a main fastener having a jamming bolt formed at one end; two sides of the main fastener are provided with guiding grooves for encasing fastener rotating shaft through which an shaft core is passed in the guiding grooves; the jamming bolt at one end of the main fastener can be arranged in the corresponding through hole of a lock shell; a protruding part is formed at the other end of the main fastener; the protruding part is matched with the other elastic component to push against the inner side of the lock shell; and the end of the lock-core rotating shaft, which is adjacent to two convex ribs, is provided with another protruding part to fit a stop part convexly arranged on the periphery of the action through hole of the door-handle cover to limit positioning. The lock has diversified effects of opening or closing convenience.

Description

technical field [0001] The present invention relates to a lock, which is mainly used to open or close a lock assembled in a safe deposit box or the like by means of a key at ordinary times, or it can be opened or closed by pressing the lock core of the lock with the hand without a key. Open the door, and simply put the door handle cover to the box to close the lock assembly design that can close the door. Background technique [0002] At present, all kinds of locks developed and manufactured in the industry are designed to prevent random opening by others, and the overall composition of the lock is designed into different anti-destructive forms according to the needs, so that users can make appropriate choices according to the application needs. The locks currently used on boxes such as safe deposit boxes usually install the door handle cover of the lock on one side of the door of the box body, and assemble the lock core sequentially in the through holes between the door han...
